Which referee showed sixteen yellow cards and four red cards in a single match in the 2006 Football World Cup?

Valentin Valentinovich Ivanov (born 4 July 1961 in Moscow) is a Russian international football referee and a former player. The son of two Olympic champions of 1956, Valentin Ivanov and Lidiya Ivanova, he lives in Moscow where he works as a physical education teacher.

The 2006 FIFA (Fédération Internationale de Football Association) World Cup was Ivanov's last major international tournament, as he reached the mandatory retirement age of 45 for FIFA referees on 4 July. In a second-round match between Portugal and the Netherlands, Ivanov issued 16 yellow cards and four red cards. The 16 cautions matched the World Cup record set in 2002 by Spanish referee Antonio López Nieto, while the four dismissals (all on the respective players' second yellow cards) set a new World Cup record. Costinha and Deco were sent off for Portugal, while it was Khalid Boulahrouz and Giovanni van Bronckhorst for the Dutch. The Netherlands were cautioned seven times, with two players given red cards following the second yellow. Portugal saw 9 yellow cards (World Cup record for one team), and two dismissals following the second yellow as well.
